Problems with 2000 Toyota Sienna ENGINE AND ENGINE COOLING

On july 22nd i was driving with my 4 young children when very suddenly i almost blacked out. i was able to call 911 and pulled over safely. i was taken to the hospital where blood tests showed nothing obviously contributed to the extreme lightheadedness and disorientation i experienced. on my 3rd trip i had a similar experience and concluded it was my minivan.it was towed to the dealership and a test drive left 3 mechanics with similar effects.they were not able to determine the cause and co2 and freon readings were negative.they steam cleaned the engine and stated the problem was no longer present.however, the problem has not gone away and our family continued to experience vomiting, headaches, dizziness, lightheadedness and disorientation whenever traveling in the van.we can no longer drive the van for fear of health and safety issues.we believe this van is defective and dangerous.

Vehicle made loud noise when engine runs which sounds like a hardened belt. dealer replaced belt which did not fix the problem. dealer replaced the pulley system which made most of the noise go away, but a slight belt like whisle can still be heard.

Engine sludged at 11,105 miles in spite of correct oil changes. tires need replacement at 13,100 miles.*ak

Our sienna was diagnosed with sludge buildup in may 2000. we were told it was necessary to replace the engine as eventually we will encounter engine failure at some point. toyota refuses to take responsiblity of this matter and continually blames the owners for lack of maintanence. there have been other owners who have encountered engine failure while driving. we are fortunate to not have had that. however, we have no peace of mind in driving this vehicle every day, with our children mind you, and knowing we could have engine failure at any time. it is very important that an investigation into this matter be done. it is obvious there is a problem as toyota has had over 3000 complaints such as ours. it is only a matter of time before someone is injured or killed as a result of toyotas negligence in this matter. is there a stipulation that someone nust be injured or killed before an agency such as yours will investigate? that makes no sense. when there is a potential for injury you must follow through. please. *ak

I took my new van 6 times to 2 dealers to get the problem fixed but they could not. i filed a case with toyota's arbitration program ncds (case#1200092) declaring my vehicle as a lemon and asking toyota to repurchase the vehicle. ncds denied my request on absurd grounds. toyota claimed in defense that the vehicle is safe to drive contradicting the owner's mannual itself. the manual warns owner not to drive the vehicle under the conditions my vehicle was in to prevent personal injury and damage to the vehicle. after getting frustrated with ncds and my new $30,000 van out of service for more than 3 months, i finally had a third dealer fix the problem. american consumers do not have to compromise safety and undergo such a pain for manufacturer's or dealers' mistakes. no safety defect listed in summary. *ak

While driving engine just all of a sudden lost power and vehicle started to slow down in the middle of traffic, possible engine or electrical malfunction. *jb
